- Study period:
- February 25, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 102 (Melting point / Melting Range); EU Method A.1 (Melting / Freezing Temperature)
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 103 (Boiling point/boiling range); EU Method A.2 (Boiling Temperature)
- Principles of method if other than guideline:
- The Differential Scanning Calorimetry (DSC) method was used for the evaluation of melting and boiling points of the test substance. Test was performed according to the SOP - SRT 028 protocol.
- GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Conclusions:
- The test substance is a solid at 20°C and 1013 hPa.
- Executive summary:
Method:
Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results:
Between 30 and 140°C, there is release of water/ solvent, followed by a degradation between 213 and 373°C, (onset at 244.1°C, enthalpy = 178.3 J/g).
Conclusion:
The test item is a solid at 1013 hPa and 20°C.
